AMD to Detail Zen 2, Navi Architectures Come Hot Chips in August

The Hot Chips conference is one of the leading-edge grounds for discussion of new silicon-bound technologies, and AMD will, as usual, take to its grounds in an effort to detail their efforts in their technology fields. The conference's organization has already confirmed a number of participants in its conference schedule, which includes the likes of Intel, Microsoft, Alibaba, NVIDIA, Tesla and of course, AMD.

AMD will be delivering two keynotes: the first, on August 19th, is simply titled "Zen 2", and will therefore deal with the underpinnings of the Zen 2 microarchitecture, which will be pervasive to all of AMD's CPU product lines. A second conference will be held on the same day by AMD's CEO Lisa Su herself, and is titled "Delivering the Future of High-Performance Computing with System, Software and Silicon Co-Optimization". On the next day, August 20th, another AMD keynote is simply titled "7 nm Navi GPU", and we expect it to follow in the footsteps of the Zen 2 conference. So, with AMD diving deep into both architectures come August... it's extremely likely the company will have launched both product lines by then. Fingers crossed. You can find the abstract on AMD's CEO Lisa Su's conference after the break.
From medicine to the frontiers of scientific research, manufacturing and entertainment-the demand for computing and graphics technologies continues growing. While we are entering a golden age of high-performance computing, it is increasingly clear that the techniques the industry has used to reach this point will not deliver similar advances over the coming years. As the gains from Moore's Law have slowed in recent years, the industry has begun to focus on new areas of innovation to maintain the historical pace of performance improvements. AMD CEO Lisa Su will discuss new techniques in system architecture, silicon design and software that will enable future generations of computing and graphics products to deliver more performance with greater efficiency.

Maybe slightly off topic, but hey...
A tiny fan on the chipset. That's just sad.

Also, how is this possible on Zen in particular? For 2 years I've been hearing how Zen being a SoC is so great because the chipset has hardly any function (hence it's cheap and so on).
What happened between X470 and X570 that they suddenly need a fan? PCIe4.0 controller?

A ~40mm slim fan - perfect addition to your cool and quiet - power efficient - Zen2 system.

Soo... and what are they going to present at computex in one week then?

Zen is SoC. But the SoC has less I/O, only 4 USB 3, 32 PCI(24 avaible on Summit Ridge, PR,).
All Reven Ridge/Picasso laptop runs in SoC mode, don't use chipset.
Chipset provide additional I/O.

I think most people has amnesia. How can they forget motherbord with chipset fan?
Then x79/x99 is 2007 chipset too as many of those had chipset fan.
AND x79 had even though it had low speed PCI-e 2.0.

@medi01 The Hot Chips one is where they will detail the architecture. Computex is a product announcement.

Yeah, how dare they build a cooler that doesn't just allow it to cook in its own heat and fail! Stupid designers cooling the chipsets so they don't burn up and kill your board. So sad.

PCI-E 4.0 runs at two times the frequency of PCI-E 3.0 (3.0 is 8Ghz and 4.0 is 16GHz), and the motherboard chipset is still made in 14nm tech and not 7nm. It's only natural it will give more heat, it's no fault of AMD's that is the case but the PCI-E 4.0 standard itself.

Speaking to Gamers Nexus, insider sources claim AMD X570 chipset may run at 15W, a notable increase in power consumption over the 6-8W thirst of past AM4 chipsets.

My biggest problem with these custom fans is if after some time it starts to make rattling noises, we can´t replace it with a better unit.

So, unless manufacturers in this case start accepting RMAs for noise, we're basically stuck.

The fans look relatively large, therefore it'll run at lower speeds to achieve longevity

I'd actually appreciate an August or September launch... It's better for my wallet.

Lmao we're back in 2008, i hope they're all well done fake, or maybe the fan is for the m2 ssds, because this would be very ridiculous.

A fan is just a low cost solution for something that should be better engineered.
Basically, a lot of silence enthusiasts have just said "no" to this platform - even if they were initially lured by Zen2's efficiency.

And we'll see PCIe4.0 motherboards without a chipset fan in few months.

Longevity is not a problem. Noise is.

You think this is OK? So you'll also be fine with DDR5 fans? Next-gen NVMe SSD fans? Where is this going?

Assuming a 7nm chipset would have solved this, then yes - it's definitely AMD's fault. But putting that aside, it's all on mobo makers. They should have provided a more clever way than a fan (which is likely the cheapest solution).

Also, for the PCIe 4.0 being so fast it needs cooling: I call b..shit.
Lately chipsets didn't even need a big heatsink - most motherboards have fairly flat, simple radiators.
I can't believe moving to PCIe 4.0 adds so much heat that they couldn't do it with a better passive solution.

AM3+ had exact same TDP and it didnt havr a fan. Sorry but mobos with fans are a thing from the past and I refuse to get a board with that nowadays. Also itbl is clear they dont have enough heat dissipation to turn it off. No go to me and not a good sign at all.

Hey you forgot it's AMD, there's no way they're doing anything wrong, it's not like we're talking about intel here.

I assume this chipset heat problem will be resolved in later iterations.

They could at least have started by using proper heat sinks with long fins instead of these metal blobs covered in plastic. :(

Therew wil be plenty of X570 mobos without a stupid fan on them to choose from. No need to panic.

Yes, I believe so. A beefy heatsink will surely do the job.

If there's a need for a fan or a beefy heatsink, there's surely some problem, or at least poor engineering, you won't solve that with fans or heatsinks, but merely patch it.

Some retard grade comments on here.

long fin Heatsink , what ,,,are we not going to fit a GPU or two overthe top of it anymore then? , it's a slim heatsink wtaf do you want them todo.

err no, epic thought fail, it's a cheap solution for affordable boards , you cant have a epic cooling solution ,on a part without much Z height , room for cooling without a fan ,i mean do describe a better way ,please do , low Z height though and low cost.

which brings point B,, Silence Enthusiasts , a f£$%$£n niche in a niche is not worth a shit.


"You think this is OK? So you'll also be fine with DDR5 fans? Next-gen NVMe SSD fans? Where is this going? "


err unless you know some other version of f%^£$^n physics , yes , yes ,it is going to go that way, smaller and more dense electronic parts make More heat not the same and not less.

so some very advanced and technical shit like micro channel cooling is a possible way to do this but some part of it will need a FAN.

as will most chipsets with upto 4xNVME drive all on pciex 4 (x40 lanes)attached to a system imho , the chipset adds pciex lanes too.



AND FINALLY, you saw a picture , thats all, you didnt test it or try it.

YOU HAVE NO CLUE HOW LOUD OR NOT THAT FAN IS at all and no idea why it's needed.

So AMD fail if fan, and fail if a heatsink :slap: :clap: you have no interest in anything AMD and have just come to the thread to troll, so what does it matter.

X58 chipset ran without fan runs to 85C, 24W

Noone gives a F*.

Now again whining? Get a life peps... it is nothing THAT BAD.

Honestly, there is a solution to everyone's fan problem.

1. A setting in motherboard bios that disables PCI-E 4.0 support and forces it to work in PCI-E 3.0 mode. You get half the performance and half the heat.

YAY.
